I was surfing the forums when a good deal popped up for a ZHP shift knob. I’ve always liked the look of the ZHP knob and figured it was time to replace the worn BMW Performance knob that I had.
(Note the wear on the right side)
Finally something to match the steering wheel!
I couldn’t be happier. It’s actually formed to the shape of my hand, unlike the BMW Performance knob. It has a much more natural feel and is easier to go through the gears.
Conclusion: It feels great with the short shifter. Money well spent!
Since Memorial Day is on Monday, I decided to take advantage of the long weekend and do some maintenance on the car. She was due for an oil change so I picked up 7 quarts of Castrol Edge, fully synthetic 5W-30. I also stopped at the dealership and picked up an oil filter kit.
I saw a few posts online about people deleting the Clutch Delay Valve for a better clutch feel. Since I was already underneath the car, I figured I might as well try removing this thing:
I popped out the locking pins with a small screwdriver and pulled the valve right out. I quickly capped both lines with my fingers because I didn’t want to lose any brake fluid. After that, I simply connected the lines back together without the valve in place. Then I got to work on bleeding the clutch. The whole process only took about a half hour with the help of a friend. Look how restrictive it is!
This car has the best clutch feel out of any car I’ve ever driven. The CVD delete paired with the BMW Performance short shift kit and the BMS clutch stop really makes for an awesome driving experience.
A big box showed up on my doorstep this weekend…
…and a BMW Performance spoiler was inside! The BMW 135i comes with a spoiler from the factory but its tiny and unflattering. This car is begging for something more aggressive. I had to install it right away.

I finally pulled the trigger on JB4 and decided to order the BMS clutch stop at the same time. Both products arrived in a few days and I installed them right away.
When I bought the car, the previous owner told me it had some sort of JB tune that was wired inline with the MAP sensor. After doing some research, I thought he was referring to JB+ which would increase boost an additional 2-5psi for an extra 20HP.
Before I could install JB4, I had to remove the JB+ chip that I thought was in the car. I removed the whole intake assembly but found no trace of the chip. I assumed the previous owner lied about it and continued on with the JB4 installation. Once I popped the ECU box open, I saw wires with electrical tape and some sort of aftermarket box with a toggle switch connected to it.
Since I was confused, I posted up a few pictures on N54tech and Terry identified it as a really old version of a pin-out JB3 tuner. The toggle switch was in the “off” position, so he advised me to carefully remove the harness and plug the wires back into the factory ECU connectors.

Beyond Redline hosted a dyno day this weekend and I wanted to find out what the car was putting down before I started modding it.
For only $60, why not?
She put down 283whp and 292wtq with only a K&N drop-in air filter and Riss Racing 3″ catback exhaust.
JB4 and catless downpipes coming soon…
